No, no, NO! It is clearly NOT "the" Pinanfarina 230SL. It may be "a" Pinanfarina 230SL, but when one talks of the former, the one on pages 92 and 93, this most definitely did not have the Sunbeam Alpine "fin" treatment in its styling.
The one shown in the photo at the first post shows sedan like headlight lighting, which is not part of that car, and not standard on the W113. The fins are not part of that car either.
This could be just be one guys "one off".
